What is the protected area under an NDB approach course? Since the

how much wider? I ask also in the context of when I should consider
myself "established" on course (for purposes of descent).

When within 10 degrees of the published course.

There is no policy or rule to support that.

He asked when he should consider himself established for the purpose
of descent. Have you got better guideline to follow when in a cockpit
looking at an instrument panel? In the absence of policy or rules, as
you say, what do you suggest a better answer would be?
